Thd distortion level
Web13 Feb 2010 · Audioholic Slumlord. Feb 13, 2010. #4. Play a vinyl recording and add at least 1.5% to the THD of the speakers. Human hearing doesn't distinguish harmonics as distortion until the percentage is fairly substantial. 1% means the added harmonic is -20dB and that would be masked by the music at most usable levels. http://www.sengpielaudio.com/calculator-thd.htm
